Answer:

Answer A, 4x^2-2x-10

Step-by-step explanation:

Since we are subtracting the first listed equation from the second, we have to switch the order of those two. The second row will all become negative (just the second, not the first) since this is subtraction. You add the numbers from there and remember to keep your coefficients and variables in line (x^2 to x^2, x to x, etc.)

Well you would first add 5/13 and 2/13, so 7/13. Then you would subtract 7 from 13. So your answer would be 6/13. Hope that helped!

Answer:

4mn/(3m+12)

Step-by-step explanation:

It is often helpful to factor expressions so that common factors can cancel.

$\dfrac{8n^2}{m^2-16}\times\dfrac{m^2-4m}{6n}=\dfrac{8mn^2(m-4)}{6n(m-4)(m+4)}=\dfrac{4mn}{3(m+4)}\\\\=\boxed{\dfrac{4mn}{3m+12}}$

Anastasy [175]

Answer:

I'll setup the problem and you can compute the answer

Step-by-step explanation:

The formula for simple:

I = P*r*t

I = interest

P = loan amount

r = interest rate per period (period = days)

n = number of periods

P = 10,170

r = .0764/365

t = 272
